To all wfiom it may concern:

Be it known that I, CHARLES N. HATFIELD, a citizen of the United States, resident of Fountain City, in the county of \Vayne and State of Indiana, have made a certain new and useful Invention in Grain and Seed Cleaners, Separators, and Grinders; and 1 declarethe. following to be a, full, clear, and some, such as will enable others skilled in the art to Which it appertains to make and use the invention, had to the accompanying reference being drawings, and to letters or figures or retorence marked thereon, which storm 2). port of this specification.

Figure 1:is a side view of the machine. Fig. 2 is a section on the line Z-2, Fig. 3. Fig. 3 is a section on the line 3-3, Fig. 2. Fig. i is a side View of the machine with the crank gear removed and the legs and shoes folded.

The invention has relation to gisin and seed cleaners separators end graders, and it consists in the novel construction and comloinetions of parts, as hereinafter set forth.

In thecccoinpanying drawings illnsil. otlng the invention, the numeral 1 designates the supporting" frame having uprights 9;, 8' at each side; 3, is the upper shoe, carrying the screen i; and 5, is the lower shoe, on W ing; the screens 6. The upper shoe is shorter than the lower shoe midis pivoted it its rear end portion at 7 to the vibratory bars 8, 8, from which it has support, said shoe at its forward end resting upon the side trams bars 9, 9, connecting the uprights at each side. The lower shoe is hung at its forward end from links 10-, 10, pivoted at their upper ends to the side bars 9f,'the shoe being supported and having sliding movement atits rear end upon an sntifiiction roller 11, car- --ried by the transverse brace 12.

The'hopper is shown at 13, and discharges upon the upper screen, said hopperhiiving a rear inclined bottom board i l, of on inclination similar to that of the upper shoe, which at its rear end portion laps under the forward end portion of the board let, there being an interval of separation wherein is located an inclined board or plate 15, said plate forming the bottom of'o suction draft passage 16,015 which the bottom hoard i l forms the top, and the lateral boards, 17

the hopper form the sides.

At the rear end of the machine is located a cylindrical fan casing 18 having plane end ends operating rod connections 33, with t intermediately of its length to the from wells parallel to the ends of the'nizichine, the inner of these end walls 19, being the end i all of the hopper host, and having as. centraloponing 20, leading; to the fan Q1 n. the fan casing, an upward extending pits-- sage 21 connecting said central opening" and. the draft passage, the passage 21* hiivin inclined converging bottom Walls 22, to or centmte the draft through the passage 16 the central opening into the "fan casing", The fan shaft 23, has projection. at one end por tion through the passage 21* and thron inner end wall 531 oi? said passage, wh it is provided with a. hovel go: conner with :1 transversely extending ro shaft 52-5, the latter shaft CELT, pinion 26, engaged by n spur Wheel 27, operated by it crank 28. train-Worse shaft is usually hung; in depern,-.--

The pinion 9G, is provid duplicate at the ends of the shaft, and pinion has n connecting; rod 32' with the per of the vibratory bars 8, at on side, said bars 8, 8, having at their ii lower shoe, the bars 8, 8, being each pivot the machine at 3%. Upon operation oi i spur gear lay its crank, the fan will he 1% titted it high speed, without too rapid ciprocction of the upper and lower shoes.

board. The lateral uprights 2, 2, of the frame will then project above this lower shoe, being of suitable length for this purpose. One pair of the opposite legs 35, nor mally in alinement and forming extensions of the uprights 2, are pivoted at their upper ends at 36 to said uprights 2 above the extensions 2* of the uprights, so that when these legs in the reversed position of the -machine are turned downward upoig their pivots they will assume approximately horizontal position at each side of the lower shoe, with the transverse brace 35 connecting the legs resting upon the lower shoe. The other pair of opposite legs 36, also normally in alinement and forming extensions of the uprights 2, are pivoted at 37' to the projecting portions 2* of the uprights below the pivots 36 of the other pair of legs, so that this second pair of legs will fold downwardly upon the first pair of legs.

Cross braces 38, 88 are provided at each side of the machine, connecting the legs at each side, the upper ends of the brace bars 38 of each pair being pivoted preferably upon the leg pivots, and the upper ends of the brace bars 38 of each pair being pivoted to the legs at 39 in horizontal alinement with the pivots of the other bars 38, but above the leg pivots at this end of the machine, so that when the upper pair of legs is raised or unfolded (the machine being upside down) the cross braces will be automatically raised or unfolded at the same time. The other or lower pair of legs is then raised or unfolded, and the notched seats l0.

of the lower ends of the bars 38, 38 engaged with the bolts 41 of the legs, the thumb nuts il being then turned home to secure the cross braces in position and brace the legs in The upper shoe hung pivotally at the rear end. and sliding at its forward end' upon the side bars of the frame will allow the heavier material that the suction draft may not have removed to drift or fall off forwardly. The

lower shoe has a lifting movement at its forward end in the reciprocating movement of the shoe, which will keep the screens of the shoe from clogging. The antifriction roller at the lower end of the lower shoe has sup? port in the upright 4.2, which may be adjusted vertically to vary the inclination of the shoe as may be required.

The screens of the shoes may be removed and replaced by others as may be required. The grain is discharged through the upper screen to the grain board 113, said board delivering to the upper screen of the lower shoe which discharges at one side at a l, the lower screen of the lower shoe discharging at the other side at if, the material passing through the lower screen of the lower shoe discharging through the spout 46 at the bottom.

It is preferred that means be provided to throw the. fan in and out of gear when desired, this means consisting usually of an endwise movable fan shaft, a lever 17 normally engaging behind the gear as to hold it in mesh with the gear 24-. When the lever a? is operated for release or raised, the fan shaft and gear 2% will move endwise under the influence of the spring 48 and the gears will no longer be in engagement.

What I claim is 1. A grain and seed cleaner separator and grader, having a hopper, a draft passage extending upwardly from and having its lower end located immediately below and adjacent to the mouth of said hopper, the lower wall of said passage having an upward projecting shoulder to cause the return of the heavier grain, a suction fan having a casing communicating with the upper end of said draft passage, and a vibratory screen located below said draft passage.

2. A grain and seed cleaner separator and grader, having a hopper, upper and lower vibratory oppositely inclined shoes carrying screens, a fan, and a fan casing having its lower wall located about on a level with the upper end of the lower of said shoes, the space between said shoes being normally open and unobstructed for convenient inspection and repairing, and the lower of said shoes being foldable upwardly into approximately horizontal position close to said fan casing.

3. In a grain and seed cleaner separator and grader, a supporting frame having uprights at each side, a lower shoe hung at its upper end within the uprights and capable of folding at its lower end within the uprights into approximately horizontal position, legs pivoted at their upper ends at different levels to and normally in alinement with said uprights, said legs being foldable into approximately horizontal position at different levels, and cross braces for the legs at each side automatically foldable and unfoldable with said legs.

In testimony whereof ture, in presence of two witnesses.
